Token Safety
by OnchainPulse in Onchain & crypto
Token safety check — answers "is this token safe to buy?" for any token: one deterministic CLEAR / CAUTION / AVOID rug & honeypot verdict across 10 chains (Solana, Base, Ethereum, BSC, Arbitrum, Polygon, Optimism, Avalanche, Robinhood Chain, Algorand). Auto-detects the chain from the address shape. Sell-simulation honeypot, mint/freeze/clawback authority, LP lock/burn, holder concentration, live liquidity — fused into one verdict. Pre-swap guardrail for trading agents and agent wallets.
